ABSTRACT

A new  Anthurium  plant particularly distinguished by having glossy orange-red, durable spathes that slowly turn brown with age, dark green, durable leaves, an erect peduncle, rich shoot formation, flowers continuously throughout the year, a compact and full plant habit and a plant height of 35.0 cm to 45.0 cm, is disclosed.

GENUS AND SPECIES

Anthurium andreanum L.

VARIETY DENOMINATION

‘Anthzupap’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘Anthzupap’. The new variety originated from ahybridization made in April 2002 in Bleiswijk, The Netherlands. Thefemale parent was a dark red Anthurium pot plant ‘4431-01’ (unpatented),while the male parent was a red Anthurium plant ‘4462-07’ (unpatented).

A single plant was selected in February 2004 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a five-year period. The new variety has been found to retain itsdistinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety were applied for in the EuropeanUnion on Dec. 8, 2008 and in Japan on Mar. 9, 2010. ‘Anthzupap’ has notbeen made publicly available more than one year prior to the filing ofthis application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands.

1) An orange-red colored medium sized glossy spathe;

2) White spadix;

3) Rich shoot formation;

4) Compact plant habit; and

5) Dark green foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs;the colors shown are as true as can be reasonably obtained byconventional photographic procedures. The photographs are of a 48-weekold plant grown in a greenhouse in Bleiswijk, The Netherlands in 2009.

FIG. 1 shows the overall plant habit, including blooms, buds andfoliage.

FIG. 2 is a close-up of the mature spathe.

FIG. 3 shows three spathes at different stages of development.

FIG. 4 shows the upper and lower leaf surfaces.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘Anthzupap’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 48-week oldplants which were planted from tissue culture in 17 centimeter pots andgrown in a glass greenhouse between 19° C. and 24° C. Observations weremade in November of 2009. Color readings were taken under 5000 luxnatural light in the greenhouse. Color references are primarily to theRHS Colour Chart of The Royal Horticultural Society of London (R.H.S.)(2001).

When the spadix matures, very small stigmata protrude. The            stigmata are evenly distributed round the spadix. The spadix            matures from base to top, slowly giving the spadix a            somewhat rough appearance.        -   Color.—Immature: RHS 15A Mature: RHS 155A Ages to: RHS 146A.-   Flowers:    -   -   Quantity per spadix.—180 to 250.        -   Spadix flower arrangement.—Bisexual, rounded in            cross-section.        -   Shape.—Rounded.        -   Size.—Length: 0.1 cm to 0.2 cm Diameter (maximum): 0.2 cm            Color: RHS 155A.-   Reproductive organs:    -   -   Stamens.—None visible.        -   Pollen.—Sparse.        -   Pollen color.—RHS 156D.        -   Pistil.—Quantity: Many Length: Less than 0.01 cm Color: RHS            155A.        -   Style.—None observed.        -   Stigma.—Shape: Ovoid Diameter: Less than 0.01 cm Color: RHS            155A.        -   Ovary.—Rarely visible.        -   Ovary color.—RHS 155A.-   Fruit and seed set: None observed.

‘Anthzupap’ is comparable to commercially available varieties ‘Anthuci’and ‘Anthabazal’. ‘Anthzupap’ differs from ‘Anthuci’ in that ‘Anthzupap’has slight spathe blistering, while ‘Anthuci’ has strong spatheblistering. Additionally, the mature leaf lobes of ‘Anthzupap’ aresmaller than the leaf lobes of ‘Anthuci’. ‘Anthzupap’ differs from‘Anthabazal’ in that ‘Anthzupap’ has orange-red spathes, while‘Anthabazal’ has red spathes.
